Check out this cool video by NASA explaining Transient Luminous Events or basically flashes and glows called blue jets, red sprites and other TLEs that appear above storms.

Blue jets pulse from the tops of intense thunderstorms and reach up toward the edge of space. Red sprites are glows in the upper atmosphere, tied to the presence of large lightning flashes but not attached to the clouds themselves.

The ISS has afforded astronauts the opportunity to photograph a number of natural light shows produced at the tops of thunderstorms as seen in below video…

In addition to following the below holiday fire safety tips from USFA and NFPA, please make sure all your exits are accessible and not blocked by decorations or trees, verify you have working smoke alarms, and learn what to do in case a fire starts in your home.

Christmas Trees

If your household includes a natural tree in its festivities, make sure you keep the tree watered.

Christmas trees account for hundreds of fires annually. Typically, shorts in electrical lights or open flames from candles, lighters or matches start tree fires. Well-watered trees are not a problem. A dry and neglected tree can be.

Dry Tree vs. High Moisture Tree Fire – The following NFPA demonstration shows how flammable a dry Christmas tree can be as opposed to a tree watered regularly.

Selecting a Tree for the Holidays – Needles on fresh trees should be green and hard to pull back from the branches, and the needles should not break if the tree has been freshly cut. The trunk should be sticky to the touch. Old trees can be identified by bouncing the tree trunk on the ground. If many needles fall off, the tree has been cut too long and, has probably dried out, and is a fire hazard.

Caring for Your Tree – Do not place your tree close to a heat source, including a fireplace or heat vent. The heat will dry out the tree, causing it to be more easily ignited by heat, flame or sparks. Be careful not to drop or flick cigarette ashes near a tree. Do not put your live tree up too early or leave it up for longer than two weeks. Keep the tree stand filled with water at all times.

Holiday LightsMaintain Your Holiday Lights – Inspect holiday lights each year for frayed wires, bare spots, gaps in the insulation, broken or cracked sockets, and excessive kinking or wear before putting them up. Use only lighting listed by an approved testing laboratory.

Do Not Overload Electrical Outlets – Do not link more than three light strands, unless the directions indicate it is safe. Connect strings of lights to an extension cord before plugging the cord into the outlet. Make sure to periodically check the wires – they should not be warm to the touch.

Do not leave holiday lights on unattended!

Holiday Decorations

Use Only Nonflammable Decorations – All decorations should be nonflammable or flame-retardant and placed away from heat vents. If you are using a metallic or artificial tree, make sure it is flame retardant.
Never Put Wrapping Paper in the Fireplace – Wrapping paper in the fireplace can result in a very large fire, throwing off dangerous sparks and embers that may result in a chimney fire.

Candle Care
Never Leave a Burning Candle Unattended – Consider using battery-operated flameless candles, which can look, smell and feel like real candles.

If You Do Use Lit Candles – Make sure candles are in stable holders and place them where they cannot be easily knocked down. Keep candles at least 12 inches from anything that can burn. Avoid using candles in bedrooms and sleeping areas.

Never Put Lit Candles on a Tree – Do not go near a Christmas tree with an open flame – candles, lighters or matches.
